Rhinitis includes many kinds; Rhinitis refers to inflammation of nasal mucosa and submucosal tissue, and commonly referred to as rhinitis refers to chronic rhinitis; The manifestations of rhinitis are varied. From the pathological changes of nasal mucosa, there are chronic simple rhinitis, chronic hypertrophic rhinitis, caseous rhinitis and atrophic rhinitis. Judging from the duration of acute remission, it can be divided into acute rhinitis and chronic rhinitis. In addition, there are some rhinitis, although the onset is slow and the course of disease is long, but there are specific pathogenic reasons, so there are specific names, such as allergic rhinitis (ie allergic rhinitis) and drug-induced rhinitis. The characteristics of various rhinitis are briefly introduced as follows: (1) Acute rhinitis: caused by acute infection, commonly known as "cold" or "cold", which may have systemic symptoms; More common in autumn and winter or at the turn of winter and spring. Generally, the condition will gradually improve after 7 ~ 14 days. Strong resistance, self-healing without treatment. It is worth noting that many precursors of acute infectious diseases have local manifestations of acute rhinitis, lacking the characteristics of infectious diseases themselves, so attention should be paid to differentiation in clinic. (2) Chronic simple rhinitis: it is a common and frequently-occurring disease, which develops from acute rhinitis. It is related to the secondary infection of bacteria, incomplete treatment and repeated attacks. Clinically, it should be differentiated from chronic hypertrophic rhinitis and chronic nasal congestion. (3) Chronic hypertrophic rhinitis: It comes from chronic simple rhinitis, which leads to hyperplasia of nasal mucosa and turbinate due to long-term chronic inflammation and congestion. At this time, mucous membrane thickens, tissue elasticity decreases, and nasal ventilation ability is poor, thus endangering the physiological function of the nose. (4) Dry rhinitis: The occurrence of dry rhinitis is closely related to climate and occupational factors. It is because the nasal mucosa is stimulated for a long time, which leads to atrophy of mucous glands and decreased secretion, resulting in dryness of mucosa and even superficial erosion. (5) Atrophic rhinitis: mainly atrophy of nasal mucosa, periosteum and turbinate; Due to the atrophy of nasal tissue, although the nasal cavity is relatively wide, the nasal mucosa has lost its normal physiological function, and patients still feel poor ventilation due to the formation of nasal trunk. It is recommended that you go to a standardized otolaryngology department for a detailed examination and make a clear diagnosis before treatment. At present, there are many methods to treat rhinitis, and the following methods can be used for conservative treatment: 1: cold compress the nasal cavity with a cold towel; 2. Wash the nasal cavity with normal saline; 3. Eat more fresh vegetables and fruits, eat more foods rich in crude fiber and water, and avoid smoking. 4. Correct bad habits such as picking your nose casually. 5. Wash your nose three times a day with a nose washer (plus normal saline). This method can increase the immune function of nasal mucosa and is a more suitable method. Surgical treatment mainly includes advanced medical equipment such as laser, microwave, low temperature plasma and sinus endoscope, which has good therapeutic effect on various rhinitis and sinusitis.
